no one ahs heard about it
they are found as element because in group 1 they react
Because
Because they are very reactive.
These elements are highly unstable because of for group1- IP is low and for group 7 electron affinity is high

Group 1 and 2 elements have 1 and 2 valence electrons respectively. Removal of these electrons will result in stable noble gas electronic configuration. Group 17 and 16 elements have 7 and 6 valence electrons respectively. Addition of 1 or 2 electrons to group 17 and 16 respectively will give them stable noble gas configuration. Hence these two groups are highly reactive and their elements will combine to form large number of compounds.

The element's group's 1 to 7 are : 1)Hydrogen 2) Heline 3)Lithiume 4)Bery limb 5)Born 6)Carbon 7) Nitrogen 8)Oxygen 9) Florine 10)Neon _______________________________________________________________ i think so 1 to 15 are almost used in the compounds. Thank You,
because god made it that way.
Group 1 elements have very low electronegativies and group 7 elements have very high electronegativities, so that both are reactive with almost every other element, the group 1 elements by donating electrons and the group 7 elements by accepting electrons.

They combine to form salts.
It is because the group 1 and 7 elements have a high reactivity. The reactivity is far too high to use on there own because the elements in these groups react with air and/or water.
